Can anyone help with a mystery plant that appeared this year without
warning. I have published a picture on..
www.mandeg.blogspot.com

Quite an attractive plant but a bit prone to blackfly..

Thanks for anyhelp.

I'm pretty sure its an invasive weed. I seem to recall that its invading the
lake District........the name escapes me, but I'll try to find out tomorrow.
